Vignette control - automatically adjusts NEF files to counteract any vignette effect and produce images with near perfect center-to-edge-to-corner brightness.

Image Dust Off - uses a reference image taken with Nikon digital SLR cameras to map out dust on the sensor and then automatically remove its effect from NEF images shot using Nikon CPU lenses.

Enhanced batch processing - automatically applies a wide variety of image adjustments and corrections to any number of files in a folder.

Remote Camera Control - controls most shooting settings, and allows images to be downloaded directly to a computer. Version 4.1 adds support for the D70 and controls, including bracketing when used with the D2H or D70.
